The Government of the Grand National Assembly (Turkish: Büyük Millet Meclisi Hükûmeti), commonly known as the Ankara Government (Turkish: Ankara Hükûmeti), was the name given to the provisional and revolutionary Turkish government based in Ankara (then known as Angora) during the Turkish Civil War (1919–1922) and during the final years of the Ottoman Empire. It was led by the Turkish National Movement, as opposed to the weak Constantinople Government, which was led by the Ottoman Sultan.
During the civil war, the Government of the Grand National Assembly commanded the army known as Kuva-yi Milliye ("National Forces"). After the war and victory over the Constantinople Government, the Ankara Government declared the end of the Ottoman Empire and the creation of modern Turkey from its ashes in 1923. The Grand National Assembly is today the parliamentary body of Turkey.
